In order to improve the accuracy of segmentation and counting of insect images，an insect image segmentation and counting method based on convolutional neural network is proposed. Based on the U-Net model，this method constructs an insect image segmentation model named Insect-Net. After inputting the complete insect image and the split insect image into the model, the features of the two images are extracted and merged. The merged features are inputted into a 1 X 1 convolutional layer to get the final segmentation results. After the obtained results are binarized, the contour detection algorithm is used to extract the contours of the insects and count them. The experimental results show that the method has higher segmentation accuracy and counting accuracy in the detection of insects, which are 89. 2% and 94. 4% respectively. The idea of deep learning and convolutional neural network effectively improves the counting accuracy of insect images, and provides a large number of non-background datasets for insect identification classification.

[Objective]The illumination, temperature and production efficiency of the ecological system in the tobacco field were significantly affected by the altitude. [Method]The article focused on the production of 32 typical peasant households in Enshi of Hubei province, the in­put and output of nutrients, energy and economic benefits in die production process of diree different altitude flue-cured tobacco(500 -900. 900 - 1200,1200 - 1500 m) were studied, and the characters of the material, energy and value flow of different altitudes were analyzed. [Result] In all the altitude of tobacco area, there were needs for controlling the amounts of N, P fertilizers and increasing the fertilizer appli­cation efficiency. In the construction of energy input, the labor energy was the highest among the energy components, and the fertilizer ener­gy followed. With the increase of altitude, the P, K and energy input to output ratio increased, and the N and value input to output ratio in­creased at first and then decreased. [Conclusion]The ratios of material, energy and value input to output at the altitude of 500 to 900 meters tobacco were minimum, and the altitude of 900 to 1500 meters was better to improve the ratio of nutrients input to output, energy efficient utilization and the ratio of value input to output.

Objective To investigate the effect of estrogen (E2) on the connexin43 (Cx43) expression of renal interlobar arteries after renal ischemia-reperfusion injury (I/R). Methods The experiment was carried out in vivo using an SD rat I/R model. SD rats were randomly divided into normal group, sham-operation group, I/R group, and estrogen-intervention group. The functional changes of the kidney were analyzed after 24 hours of I/R; nephridial tissue section was stained by hematoxylin-eosin (HE), and Paller scores were used to evaluate the degree of kidney damage. Pressure myography was utilized to detect the vasomotor function of renal interlobar arteries. Immunofluorescence technique, qRT-PCR and Western blot were applied to determine the expression of Cx43 in renal interlobar arteries in different groups. Results Estrogen markedly decreased the levels of Cr and BUN in the serum of I/R rats (P<0.05), and the damage of the kidney tissue could be improved noticeably. The vasomotor rate of renal interlobar arteries was (24.80±3.70)% after I/R and (41.60±3.50)% after treatment with estrogen, which was higher than that of I/R group (P<0.05). The expression of Cx43 was lower in renal interlobar arteries of estrogen-intervention group than that in I/R group (P<0.01). Conclusion Estrogen may reduce vascular tension and boost dilation of the artery by inhibiting Cx43 expression and GJ function. Therefore, estrogen may attenuate the damage of I/R and improve renal function. [ABSTRACT FROM AUTHOR]
